Description

According to the present invention, for example, an exchange unit having a built-in filter or the like and capable of forming a pipeline by being detached and detachably attached as a part of an existing pipeline, and a flow circuit system using the same. Regarding.

In a pipeline for the purpose of filtering fluid, a filter or the like is built in a part of the pipeline, and a replaceable unit that can be detached and replaced is arranged. For example, when a predetermined amount of filtration is completed, the old replacement unit is removed and replaced with a new replacement unit. Such a pipeline lacks a portion of the pipeline between the end of the upstream pipeline and the end of the downstream pipeline. The replacement unit has a structure that can be detachably attached between the end of the upstream pipeline and the end of the downstream pipeline. The exchange unit has a flow path formed inside, and has a flow path inlet and a flow path outlet at both ends of the flow path. A filter or the like is arranged in the flow path. Generally, the end of the upstream pipeline and the end of the downstream pipeline are configured as part of the manifold, and when the replacement unit is attached to the manifold, the flow path inlet of the replacement unit becomes the upstream pipe. It joins with the end of the road and the outlet of the flow path joins with the end of the downstream pipeline. This completes the flow circuit system line by connecting the flow path of the replacement unit to the partially missing line.

Patent Document 1 discloses an example of an exchange unit capable of forming a pipeline by being detachably attached and detachably attached as a part of an existing pipeline. In Patent Document 1, the distance between the end of the pipeline on the upstream side of the manifold and the end of the pipeline on the downstream side is invariant, and the replacement unit is a flow of the replacement unit between these ends. It is attached by pivotal operation with either one of the road entrance and the flow path outlet as the pivot axis. However, in the attachment of the replacement unit by the pivotal operation, since the range of motion at the end opposite to the pivot is large, the rubbing distance of the seal member is long, the wear of the seal member is large, and the problem of dust generation occurs.

Further, in general, in an exchange unit having flow path ends at both side ends of the main body, the distance between the flow path ends of the exchange unit varies between solids due to manufacturing tolerances. If the distance between the flow path inlet and the flow path outlet of the replacement unit varies, the replacement unit causes the distance between the end of the pipeline on the upstream side of the manifold and the end of the pipeline on the downstream side of the manifold. In a manifold that is immutable, the amount of variation is the same as the joint position between the end of the pipeline on the upstream side of the manifold and the flow path inlet of the replacement unit, and the end of the pipeline on the downstream side of the manifold and the replacement unit. There is a problem that the joint position with the flow path outlet is displaced. Further, leakage occurs because the desired pressing force does not reach the seal member, or a load greater than the desired pressing force is applied to the seal member , leading to problems such as increased wear of the seal member.

On the other hand, Patent Document 2 discloses a water purifier cartridge used in a sink. Here, a manifold provided with a slidable sleeve pipe and a water purifier cartridge are disclosed, and the distance between the end of the upstream pipe and the end of the downstream pipe on the manifold side varies. do not do. In the water purifier cartridge disclosed in Patent Document 2, one end of the flow path of the water purifier cartridge is screwed into one end of the pipeline of the manifold, and the sleeve pipe of the manifold extends and is connected to the other end of the pipeline of the manifold. The water purifier cartridge to be used is disclosed. However, the coupling by screwing is complicated for the operator, and for a fluid with high pressure, a form in which a slidable sleeve pipe extends to the other end of the pipeline of the manifold and is bonded is adopted. Can not. Further, in an industrial filtration device in which the object to be filtered is liable to solidify, if the movable portion is arranged on the manifold, the fixed substance contained in the fluid is fixed to the movable portion of the movable portion, which is disadvantageous.

In order to detachably attach from a predetermined direction between the first pipeline end portion and the second pipeline end portion in a flow circuit manifold having a first pipeline end portion and a second pipeline end portion. The manifold has a first facing surface whose first pipeline end is narrowed in the mounting direction, and a second facing surface whose second pipeline end is narrowing in the mounting direction. , The exchange unit has a first flow path end having a first complementary surface having a shape complementary to the first facing surface and a second complementary surface having a shape complementary to the second facing surface. The solution is to have a replacement unit with a second flow path end.

(Example 1)
The present invention will be described with reference to FIGS. 1 to 5. FIG. 1 shows a manifold 1 as part of a flow circuit. The manifold 1 includes a first pipeline end portion 11 and a second pipeline end portion 12. The flow circuit to which the manifold 1 is attached has a missing portion of the flow path between the first pipeline end portion 11 and the second pipeline end portion 12. The first pipeline end portion 11 and the second pipeline end portion 12 are arranged so as to face each other so as to face each other, and each of them may be, for example, a block-shaped member. For example, a pipeline 11a connected to a fluid source (not shown) is connected to the first pipeline end 11 to form an upstream side of a flow circuit, while a fluid is connected to the second pipeline end 12. The pipeline 12a connected to the discharge destination (not shown) of the above can be connected to form the downstream side of the flow circuit. However, the relationship between the upstream and the downstream in the manifold 1 is an example, and can be set in reverse. Hereinafter, in the present specification, as an example, the first pipeline end 11 side will be described as the upstream side, and the second pipeline end 12 will be described as the downstream side.

Each of the first pipeline end portion 11 and the second pipeline end portion 12 has a facing surface 11b and a facing surface 12b facing each other. A first conduit end 11 and the second conduit end 12 is fixed, the distance between the mutually pairs directed surfaces 11b and the surface 12b is unchanged. During this distance, the replacement unit 3 is detachably attached so as to be fitted as it is by a translational operation from the lateral direction with respect to the direction from the first pipeline end 11 to the second pipeline end 12. Be done. Here, the "lateral direction with respect to the direction from the first pipeline end 11 to the second pipeline end 12" is defined as the "attachment direction" when the replacement unit 3 is attached in translational operation. The facing surface 11b of the first pipeline end portion 11 is inclined with respect to the mounting direction. Further, the facing surface 12b of the second pipeline end portion 12 is also inclined with respect to the mounting direction. The inclination direction of the facing surface 11b of the first pipeline end 11 of the manifold 1 and the facing surface 12b of the second pipeline end 12 narrows toward the mounting direction when the replacement unit 3 is mounted in translational operation. It is a form of going.

That is, the manifold 1 forming a part of the flow circuit system in the present invention is a missing part of the flow path which is a part of the flow circuit, and the first pipeline end 11 and the other end which are one end of the missing part. The flow circuit system is completed by joining the internal flow path of the exchange unit 3 to the barrel second pipeline end portion 12. Then, at one end of the manifold 1, which is a missing portion of the flow path, a facing surface 11b and a facing surface 12b that are inclined with respect to the mounting direction are provided, with the lateral direction from one end to the other end as the mounting direction. Each of the first pipeline end 11 at one end and the second pipeline end 12 at the other end is provided.

The exchange unit 3 includes a first flow path end portion 31, a second flow path end portion 32, and a main body portion 33. The first flow path end portion 31 extends to one end side of the main body portion 33, and the second flow path end portion 32 extends to the main body portion 33 corresponding to the opposite side of the end portion. The inside of the main body 33 is hollow, and for example, a filter or the like 34 is arranged in the hollow portion. The filter or the like 34 is a filter member , an ion exchange resin, an adsorbent such as zeolite or diatomaceous earth, or a member in which the adsorbent and the filter member are combined. Inside the exchange unit 3, a flow path is formed in the exchange unit 3 of FIG. 1 from the first flow path end 31 to the second flow path end 32 through a filter or the like 34, as shown by a broken line. ing. It is assumed that the replacement unit 3 in the first embodiment is manufactured by assembling between the first flow path end 31 and the second flow path end 32 while keeping the manufacturing tolerance. Therefore, since the total length is long, the variation that occurs between solids is relatively large in the production of the replacement unit 3.

A connection portion between the end of the flow path of the replacement unit 3 and the end of the flow path on the manifold side will be described with reference to FIGS. 2 to 4. FIG. 2 shows a connection portion between the end of the flow path of the replacement unit 3 and the end of the flow path on the manifold side as the most typical example. FIG. 3 shows a connection portion between the end portion of the flow path of the exchange unit 3 of another aspect and the end portion of the flow path on the manifold side. FIG. 4 is a diagram showing the flow path end of the replacement unit 3 as viewed from the end of the flow path on the manifold side. FIG. 5 shows a connection portion between the end portion of the flow path of the exchange unit 3 in which the arrangement of the seal member is changed and the end portion of the flow path on the manifold side.

The first flow path end portion 31 of the exchange unit 3 has a complementary surface 31a having a shape complementary to the facing surface 11b of the first pipeline end portion 11 of the manifold 1. Similarly, the second flow path end portion 32 of the replacement unit 3 has a complementary surface 32a having a shape complementary to the shape of the facing surface 12b of the second pipeline end portion 12 of the manifold 1. As a typical example of the complementary shape, when the shape of the facing surface 11b of the first pipeline end 11 of the manifold 1 and the shape of the facing surface 12b of the second pipeline end 12 are flat surfaces having an inclination, respectively. The complementary surface 31a and the complementary surface 32a are inclined surfaces that complement each other. The complementary surface has the same inclination angle of the opposing surface 11b at an arbitrary position and the inclination angle of the complementary surface 31a at the corresponding position, and also has an inclination angle of the opposite surface 12b at an arbitrary position and the corresponding complement. It means that the inclination angles of the surfaces 32a are the same. Further, the inclination angle referred to here includes an angle in the tangential direction of the curve. That is, complementary means that the facing surface 11b and the facing surface 12b are curved surfaces, while the complementary surface 31a and the complementary surface 32a are complementary curved surfaces in which the tangents at the corresponding positions are the same. Includes. The same applies to the combination of a curved surface and a flat surface. Further, the complementary shape does not mean a connection such as fitting, and there is a manufacturing tolerance between the facing surface 11b of the first pipeline end 11 of the manifold 1 and the complementary surface 31a of the replacement unit 3. It means that the boundary surfaces have the same shape on the premise that the minimum necessary gaps such as surface roughness are uniformly generated.

The most typical relationship between the facing surface 11b of the first pipeline end 11 of the manifold 1 and the complementary surface 31a of the replacement unit 3 is the embodiment shown in FIGS. 1 and 2 as Example 1. That is, as shown in FIG. 2, in the first embodiment, the facing surface 12b of the second pipeline end portion 12 of the manifold 1 is an inclined plane having an inclination, and the complementary surface 32a having a shape complementary thereto is It is an inclined plane having an inclination of the same angle as the facing surface 12b. That is, the complementary surface 32a is in a parallel relationship with the facing surface 12b. Similarly, the facing surface 11b of the first pipeline end 11 of the manifold 1 is also an inclined plane having an inclination, and the complementary surface 31a having a shape complementary thereto is an inclined plane having the same inclination as the facing surface 11b. Is. Further, in the present embodiment, the inclination direction of the facing surface 11b of the first pipeline end portion 11 of the manifold 1 and the inclination direction of the facing surface 12b of the second pipeline end portion 12 are inclination directions around the same axis. The directions are opposite to each other, and the relationship is narrowed in the "mounting direction" of the replacement unit 3. Similarly, the complementary surface 31a of the first flow path end 31 of the exchange unit 3 and the complementary surface 32a of the second flow path end 32 are in a relationship of narrowing in the "mounting direction" of the exchange unit 3. However, the angles of inclination may be the same or different.

The complementary surface 31a of the first flow path end 31 of the exchange unit 3 and the complementary surface 32a of the second flow path end 32 of the exchange unit 3 have a seal member 31b such as an O-ring and a seal member 32b, respectively. Have been placed. The seal member 31b and the seal member 32b are pressed against the facing surfaces and come into close contact with each other. In the case of the example of FIG. 2, the seal member 32b is arranged on the complementary surface 32a of the second flow path end 32 of the replacement unit 3, and the complementary surface 32a of the second flow path end 32 is pressed by the pressing force on the replacement unit 3. Is pressed against the facing surface 12b of the second pipeline end 12 on the manifold 1 side and comes into close contact with the surface. Although not shown in FIG. 2, the sealing member 31b is similarly set to be in close contact with the complementary surface 31a of the first flow path end 31 by the pressing force on the replacement unit 3. In the example of FIG. 2, the seal member 31b and the seal member 32b are arranged on the side of the replacement unit 3, but may be arranged on the facing surface 11b and the facing surface 12b of the manifold 1. Further, in FIG. 2, the seal member 31b and the seal member 32b are arranged as members separate from the replacement unit 3 as represented by the O-ring, but as shown in FIG. 3, the seal member 32b is arranged. It may be an elastic protrusion that protrudes toward the facing surface 12b as a part of the complementary surface 32a of the second flow path end portion 32 of the exchange unit 3. As shown in FIG. 4, the seal member 32 is arranged so as to completely surround the mouth of the pipeline 32c of the second flow path end 32 of the exchange unit 3. The complementary surface 31a of the first flow path end 31 of the exchange unit 3 is the same as the complementary surface 32a of the second flow path end 32.

As described above, the facing surface 11b of the first pipeline end 11 of the manifold 1 and the complementary surface 31a of the first flow path end 31 of the replacement unit 3 are typically parallel with the same inclination angle. It is convenient to do. However, since the facing surface 11b of the first pipeline end 11 of the manifold 1 and the complementary surface 31a of the first flow path end 31 of the replacement unit 3 come into contact with each other via the seal member 31b, they are complementary to the facing surface 11b. The inclination angle does not necessarily have to be the same as that of 31a. For example, as shown in FIG. 3, all regions surrounding the pipeline 32c on the facing surface 11b of the second pipeline end 12 of the manifold 1 and the complementary surface 31a of the first flow path end 31 of the replacement unit 3. The angles may be different as long as the seal member 32b is in close contact with both the facing surface 11b and the complementary surface 31a without forming a gap in the seal member 32b. Further, as long as the seal member 32b is in close contact with both the facing surface 11b and the complementary surface 31a without forming a gap, one may be a flat surface and the other may be a curved surface.

Further, as shown in FIG. 2, the flow path 32c in the second flow path end portion 32 of the exchange unit 3 has a funnel-shaped spreading portion 35. If the distance between the first flow path end 31 and the second flow path end 32 is different between individuals due to variations in manufacturing tolerance, the second flow path end of the exchange unit 3 is used for each individual. part 32 is thus shifted to the left or right side of FIG. 2 (the back side of the mounting direction of the exchange unit 3) (front side of the mounting of the replacement unit 3 direction) in FIG. 2, the passage 32c is expanded portion 35 By having, the flow path 32c in the second flow path end 32 of the replacement unit 3 is located on the back side or the front side in the mounting direction with respect to the line 12a of the second line end 12 on the manifold 1 side. Even if it is displaced, the pipeline 12a of the second pipeline end 12 on the manifold 1 side and the flow path 32c in the second flow path end 32 of the replacement unit 3 can be fluidly coupled. Is. Further, the expansion portion 35 of the flow path is arranged not on the side of the replacement unit 3, but on the manifold 1 side, that is, on the pipeline 11a side of the second pipeline end portion 11 and the pipeline 12a side of the second pipeline end portion 12. May be good. However, the seal member 32b should be arranged on the side of the replacement unit 3 or the manifold 1 on which the spread portion 35 is arranged. For example, it is not preferable to arrange the spreading portion 35 in the replacement unit 3 and the sealing member 32b on the manifold 1 side. The same applies to the first flow path end 31 of the exchange unit 3.

Further, FIG. 5 shows the relationship between the second pipeline end portion 12 on the manifold 1 side and the second flow path end portion 32 of the replacement unit 3. If the facing surface 12b of the second pipeline end 12 on the manifold 1 side and the complementary surface 32a of the second flow path end 32 of the exchange unit 3 have a complementary shape, the exchange unit 3 can be translated. When a pressing force F is applied in the "mounting direction" at the time of mounting, the complementary surface 32a of the second flow path end portion 32 of the replacement unit 3 pushes the facing surface 12b of the second pipeline end portion 12 by the component force f. It will be. Here, assuming that the distance between the first flow path end 31 and the second flow path end 32 of the replacement unit 3 varies due to manufacturing tolerances, and that short and long ones are mixed, the manifold 1 side If the facing surface 12b of the second pipeline end portion 12 and the complementary surface 32a of the second flow path end portion 32 of the exchange unit 3 have a complementary shape, the pressing force F is the second flow path end portion 32. A component force f is uniformly generated at the interface between the complementary surface 32a of the above and the facing surface 12b of the second pipeline end 12 on the manifold 1 side, and the sealing member 32b is always pressed on the manifold 1 side with the same pressing force. It is possible to bring the second pipeline end portion 12 into close contact with the facing surface 12b. If, in variation in manufacturing tolerances, even as the distance is different between the first channel end 31 and the second channel end 32, as long as the inclination angle Ru same plane der arises a component force theory Is the same. The same applies to the facing surface 11b of the first pipeline end 11 on the manifold 1 side.

As a pressing means for fixing the replacement unit 3 to the manifold 1 while pushing the replacement unit 3 in the mounting direction with the pressing pressure F, for example, a belt (not shown) may be used. In addition, a method of fixing the replacement unit 3 to the manifold 1 while pushing the replacement unit 3 in the mounting direction with the pressing force F can take various forms.

Have complementary surface 31a of the first flow path end 31 of the exchange unit 3 has a complementary shape to the facing surface 11b of the first pipe end portion 11 of the manifold 1, the second channel end 32 of the exchange unit 3 As long as has a complementary surface 32a having a shape complementary to the shape of the facing surface 12b of the second pipeline end 12 of the manifold 1, the manifold 3 is pushed in the mounting direction with a pressing force F by any method. When fixed to 1, the seal member 31b and the seal member 32b are pressed against the facing surface 11b of the first pipeline end 11 on the manifold 1 side and the facing surface 12b of the second pipeline end 12 with a predetermined pressing force. be able to.

In the first embodiment, the complementary surface 31a of the first flow path end 31 of the replacement unit 3 and the facing surface 11b of the first pipeline end 11 of the manifold 1 are joined, and the second flow path end 32 of the replacement unit 3 is joined. By joining the complementary surface 32a of the manifold 1 and the facing surface 12b of the second pipeline end portion 12 of the manifold 1, along the axis in the direction from the first pipeline end portion 11 of the manifold 1 to the second pipeline end portion 12. It is for positioning. Therefore, positioning along an axis in the direction perpendicular to this is not possible. Therefore, the width of the two side surfaces adjacent to the complementary surface 31a of the first flow path end portion 31 of the replacement unit 3 and the width of the two side surfaces adjacent to the facing surface 11b of the first pipeline end portion 11 of the manifold 1. By matching the above, positioning is performed along the direction perpendicular to the direction from the first pipeline end 11 to the second pipeline end 12 of the manifold 1. Therefore, in the positioning along the direction perpendicular to the direction from the first pipeline end 11 to the second pipeline end 12 of the manifold 1, the first flow path end 31 of the replacement unit 3 is the first manifold 1. This is done by fitting to the pipeline end portion 11.

(Example 2)
Example 2 as a peculiar example of this example is the form shown in FIG. Figure 6 is a 90 degrees with respect to the mounting direction of the inclination angle exchange unit 3 of the opposite surface 11b of the first pipe end portion 11 of the manifold 1, the inclination angle of the facing surface 12b of the second conduit end 12 Is the direction opposite to the inclination angle of the facing surface 11b of the first pipeline end portion 11, which is an example of 90 degrees. That is, the facing surface 11b of the first pipeline end 11 of the manifold 1 and the facing surface 12b of the second pipeline end 12 are vertically flat surfaces, respectively, and the first flow path end 31 of the replacement unit 3 The complementary surface 31a of the above and the complementary surface 32a of the end 32 of the second flow path also form a vertical plane. In such a case, if the replacement unit 3 is fixed to the manifold 1 while being pushed in the mounting direction with the pressing force F, the pressing force F remains as it is, and the complementary surface 31a and the first of the first flow path end 31 of the replacement unit 3 The complementary surface 32a of the two flow path end portions 32 presses the facing surface 11b of the first pipeline end portion 11 of the manifold 1 and the facing surface 12b of the first pipeline end portion 12.

(Example 3)
The third embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 shows the replacement unit 3 of the third embodiment. FIG. 8 is a modified example of the replacement unit 3 in that case. In the first embodiment, the complementary surface 31a of the first flow path end 31 of the replacement unit 3 and the facing surface 11b of the first pipeline end 11 of the manifold 1 are joined, and the second flow path end 32 of the replacement unit 3 is joined. By joining the complementary surface 32a of the manifold 1 and the facing surface 12b of the second pipeline end portion 12 of the manifold 1, along the axis in the direction from the first pipeline end portion 11 of the manifold 1 to the second pipeline end portion 12. It is for positioning. However, in the third embodiment, only the second flow path end 42 of the replacement unit 3 and the second pipeline end 14 of the manifold 1 satisfy the functions of the first embodiment. Then, in the third embodiment, in the first flow path end portion 41 of the replacement unit 3 and the first pipeline end portion 13 of the manifold 1, the first pipeline end portion 13 of the manifold 1 goes toward the second pipeline end portion 14. Positioning is performed along the direction perpendicular to the direction.

The inclination direction of the facing surface 13b of the first pipeline end 13 of the manifold 1 and the inclination direction of the facing surface 14b of the second pipeline end 14 are deviated by 90 degrees. Both have an inclination that narrows toward the mounting direction of the replacement unit 3. Further, on the side of the first pipeline end portion 13 of the manifold 1, the first pipeline end portion 13 of the manifold 1 has an facing surface 13c facing the facing surface 13b, and the facing surface 13b and the facing surface 13c Has an inclination that narrows toward the mounting direction of the replacement unit 3. On the side of the second pipeline end portion 14 of the manifold 1, the second pipeline end portion 14 of the manifold 1 has an facing surface 14c facing the facing surface 14b, and the facing surface 14b and the facing surface 14c are , Has an inclination that narrows toward the mounting direction of the replacement unit 3.

The same applies to the exchange unit 3. The inclination direction of the complementary surface 41a of the second flow path end 41 of the exchange unit 3 and the inclination direction of the complementary surface 42a of the second flow path end 42 are deviated by 90 degrees. Both have an inclination that narrows toward the mounting direction of the replacement unit 3. Further, on the side of the first flow path end portion 41 of the exchange unit 3, the first flow path end portion 41 of the exchange unit 3 has a complementary surface 41d on the opposite side of the complementary surface 41a, and is complementary to the complementary surface 41a. The 41d has an inclination that narrows toward the mounting direction of the replacement unit 3. In the side of the second channel end 42 of the manifold 1, and its complementary surface 42a, has a complementary surface 42d on the opposite side, the complementary surface 42 d complementary surface 42a, the mounting direction of the exchange unit 3 It has a slope that narrows toward it. That is, the inclination direction of the facing surface 13b of the first pipeline end portion 13 of the manifold 1 and the inclination direction of the facing surface 14b of the second pipeline end portion 14 are set to the inclination directions around the same axis, and the first flow of the replacement unit 3 It is held at both ends in a stretched manner between the complementary surface 41a of the roadside portion 41 and the complementary surface 42a of the second flow path end portion 42.

In the third embodiment, one axial positioning in the direction from the first pipeline end 13 to the second pipeline end 14 of the manifold 1 is performed not at both ends of the replacement unit 3 but at one end of the replacement unit 3. This is done only on the department side. In this case, it is assumed that the manufacturing tolerance is kept with high accuracy only on one side of the replacement unit 3, for example, only on the second flow path end 42 side. If the manufacturing tolerance is kept with high accuracy only on the second flow path end 42 side of the exchange unit 3, the distance between the complementary surface 42a and the complementary surface 42d at the second flow path end 42 of the exchange unit 3 will be. Since the distance is shorter than the distance between the first flow path end 41 and the second flow path end 42 in the case of the first embodiment, the manufacturing variation in the third embodiment is smaller than that in the case of the first embodiment. It can be supported only on one side of the exchange unit 3, for example, only on the second flow path end portion 42 side. Since the tolerance of the total length is relatively low also in the case of the third embodiment, it is disadvantageous to take the inclination direction around the same axis as in the first embodiment. In a third embodiment, the inclination direction of the complementary surface 41a and the second channel end 4 second complementary surface 4 2a of the first channel end 41 and the inclined direction of different axis.

As shown in FIG. 7, the facing surface 14b is provided on the upper side of the second pipeline end portion 14 of the manifold 1, and the facing surface 14c is provided on the side facing the facing surface 14b. A second flow passage end portion 4 2 of the exchange unit 3 has a complementary surface 42a so as to correspond to the opposing surface 14b on the upper side of the second conduit end 14 of the manifold 1, to correspond with the opposed surface 14c Has a complementary surface 42d. The facing surface 42b and the facing surface 42d are narrowed in the mounting direction of the replacement unit 3. Correspondingly, the complementary surface 42a and the complementary surface 42c of the exchange unit 3 are also narrowed in the mounting direction of the exchange unit 3. As long as this is done, the second flow path end 42 of the replacement unit 3 is inserted into the inside of the second pipeline end 14 of the manifold 1 in the mounting direction of the replacement unit 3, and the complementary surface 42a of the replacement unit 3 is a manifold. If the facing surface 14b of 1 is pressed and the complementary surface 42c of the replacement unit 3 presses the facing surface 14c of the manifold 1, the second pipeline end 14 of the manifold 1 and the second flow path end of the replacement unit 3 are pressed. The seal member 42b can be joined by pressing the seal member 42b with an appropriate pressure. At this time, as in the case of the first embodiment, in either the pipeline of the second pipeline end 14 of the manifold 1 or the pipeline of the second flow path end 42 of the replacement unit 3 at the joint, It is preferable to provide the spreading portion 35 as described in the first embodiment.

A first conduit end 1 3 of the manifold 1, the same applies to the side of the first flow passage end portion 41 of the exchange unit 3. The inclination direction of the complementary surface 41a of the second flow path end 41 of the exchange unit 3 and the inclination direction of the complementary surface 42a of the second flow path end 42 are deviated by 90 degrees. The facing surface 13b is provided on the upper side of the first pipeline end portion 13 of the manifold 1, and the facing surface 13c is provided on the side facing the facing surface 13b. A complementary surface 41a is provided on the side of the first flow path end 41 of the replacement unit 3 so as to correspond to the facing surface 13b of the first pipeline end 13 of the manifold 1, while corresponding to the facing surface 13c. Has a complementary surface 41d. The facing surface 13b and the facing surface 13c are narrowed in the mounting direction of the replacement unit 3. Correspondingly, the complementary surface 41a and the complementary surface 41 d of the exchange unit 3 also narrows the mounting direction of the exchange unit 3. As long as this is done, the first flow path end 41 of the replacement unit 3 is inserted into the inside of the first pipeline end 13 of the manifold 1 in the mounting direction of the replacement unit 3, and the complementary surface 41a of the replacement unit 3 is the manifold 1. When the facing surface 13b of the manifold 1 is pressed and the complementary surface 41d of the replacement unit 3 presses the facing surface 13c of the manifold 1, the first pipeline end 13 of the manifold 1 and the first flow path end 41 of the replacement unit 3 are pressed. , The seal member 41b can be pressed and joined with an appropriate pressure. Again, as in the case of the first embodiment, it is carried out in either the pipeline of the first pipeline end 13 of the manifold 1 or the pipeline of the first flow path end 41 of the replacement unit 3 at the joint. It is preferable to provide the spreading portion 35 as described in Example 1.

That is, in the third embodiment, the first pipeline end portion 13 of the manifold 1 has a facing surface 13b which is a first facing surface and a facing surface 13c which is a second facing surface facing the first facing surface, and the replacement unit 3 at that portion. The first flow path end 41 side has a complementary surface 41a which is a first complementary surface and a complementary surface 41d which is a second complementary surface located on the opposite side thereof. On the other hand, the second pipeline end portion 14 has a facing surface 14b which is a third facing surface and a facing surface 14c which is a fourth facing surface facing the third facing surface, and the second flow path end portion 42 of the exchange unit 3 at that location. On the side, there is a complementary surface 42a which is a third complementary surface and a complementary surface 42d which is a fourth complementary surface located on the opposite side.

Further, although the first flow path end portion 31 and the second flow path end portion 32 of the exchange unit 3 have been described as a block-shaped member extending from the main body portion 33, the first exchange unit 3 shown in FIG. similar to the flow channel end 52, the complementary surfaces 5 2 a may be directly attached to the main body portion 33. Even in this case, the relationship between the complementary surface 52a and the complementary surface 52d is the same. The same applies to the relationship between the complementary surface 52a and the facing surface 13b facing the complementary surface 52a, and the relationship between the complementary surface 52a and the facing surface 13b facing the complementary surface 52a.

In Examples 1 to 3, the first flow path end 31 and the second flow path end 32, and the first flow path end 41 and the first flow path end 42 of the exchange unit 3 have a block shape. .. The advantages of this are, for example, in the case of the first embodiment, from the facing surface 11b of the first pipeline end 11 of the manifold 1 to the facing surface 12b of the second pipeline end 12, and the second of the replacement unit 3. By utilizing the inclined surface on the complementary surface 31a of the flow path end 31 and the complementary surface 32a of the second flow path end 32, the second flow path end 31 of the exchange unit 3 caused by the dimensional tolerance in manufacturing. The difference in position between the complementary surface 31a of the above and the complementary surface 32a of the second flow path end 32 can be eliminated. This has an advantageous effect in adjusting the pressing force and the pipe position as described above. Further, in the complementary surface 31a of the second flow path end 31 of the exchange unit 3 and the complementary surface 32a of the second flow path end 32, the lateral surface of the complementary surface 31a and the complementary surface 32a is inclined in the inclined direction. There is also an aspect that has the advantageous effect of guiding correctly. For example, in theory, the complementary surface 31a and the complementary surface 32a need only be inclined at the portion of the pipeline, but they may have a form as shown in FIG. 9, for example. In this way, that is, in the complementary surface 31a of the first flow path end 31 or the complementary surface 32a of the second flow path end 32, only the pipe portion is with the facing surface 11b of the first pipeline end 11 of the manifold 1. The shape is complementary so as to correspond to the facing surface 12b of the second pipeline end portion 12. In this case, since the area of the inclined surface is small, the rib 51 can be arranged to have the effect of the block-shaped side surface of the second flow path end portion 32 of the replacement unit 3.
